Traditional Box Sash Windows
The traditional ‘box sash window’ operates by counterbalancing the weight of the sash against weights attached to cord and passed over a pulley. These weights (generally lead, steel or cast iron) travel up and down in a box concealed within the window frame, hence the name ‘box sash windows’ A parting slip (wagtail) is often suspended within the box to prevent collision of the weights. Access to the weights is by means of removable pockets, usually cut into the insides of the box lining.
